Zinc selenide/ zinc sulphide optical components
What are you looking for in Stock?
Zinc Sulphide (ZnS) is a widely used IR transmitting material in windows, lenses and other optical components and is sometimes referred to as Cleartran™. The material transmits at about 50% between 0.4 -12μm before dropping off to zero transmission around 15μm. Its low absorbance in the IR spectrum makes it desirable for CO2 lasers operating at 10.6μm. Zinc Sulphide has a pale yellow to clear appearance and a hardness of HK160. Although the material is resistant to thermal shock, it is not recommended for harsh environments.
Zinc Selenide has a range of applications including optical windows in FLIR (Forward Looking Infrared) systems, meniscus, spherical or cylindrical lenses and resonator windows in CO2 lasers.
